kamlesh kumar mehta  (7 years ago)

% of married = 85%
% of phone = 70%
% of car = 75%
% of house = 80.
Therefore,
% of not married = 15%
% of not having phone = 30%
% of not owning car = 25%
% of not having house = 20%
So, % of not having any of these things = 15 +25+ 30 + 20 = 90%
So, % of people having all = 100 -90 = 10%
Thus, people = 10.
